Study Notes
Statistics in Assessment
- Descriptive statistics report or describe the features or characteristics of data
- Inferential statistics generalize about a larger population based on sample data
- Non-parametric statistics are another type of statistics
- Errors can occur in the assessment process, including sources of error
Inferential Statistics
- Characterized by using sample data to generalize about a larger population
- Example: Dr. Ubaldo uses sample data to generalize about a larger population in his study
Measures of Central Tendency
- Mode is the most frequently occurring value in a dataset
- Median is the middle value in a dataset when it is in order
- Mean is the average value in a dataset
- Example: Find the mode in the dataset: 44, 45, 46, 37, 45 → 45
Descriptive Statistics
- Primary concerns in descriptive statistics include mean, mode, and standard deviation
- Example: Dr. Rivera wants to know the standard deviation of scores in his self-made test on the Filipino trait, Pagkamahiyain
Testing and Assessment
- A score can be a letter or other codes that represent the performance quality of a test
- Interview as an assessment tool can be ideal since a wealth of information is being obtained
- Panel interview involves more than one interviewer participating in the assessment process
- Portfolio assessment is mainly concerned with the work products of an individual
Psychological Concepts
- Traits refer to discernible, comparatively permanent differences between two individuals
- Psychological state refers to a person's temporary emotional or mental condition
- Example: Mary, a very quiet person, acts like a "saint" around her friends and consistently lives by her values in life
Psychometric Concepts
- Norms are standards or benchmarks used to evaluate and interpret individual test scores
- A sample is a subset of individuals from a larger population
- A population is the complete universe of individuals with at least one common, observable characteristic
